Abstract Scope The sensitivity analysis of electromechanical properties for PZT-4 has been performed using the complex variable finite element method (ZFEM) on a two-dimensional geometry. A thin plate model is subjected to a uniform boundary load to induce mechanical strain yielding variations in the electric potential field. The numerical results from mechanical displacements and electric potential fields are verified against the solution from a commercial software. The first order derivatives obtained from ZFEM illustrate the sensitivity of material properties as design parameters for real time tunability of manufacturing processes in additive manufacturing. Results show that the largest sensitivities emerge from elastic constants and followed by the dielectric and piezoelectric constants in the poling direction affecting the mechanical deformation and electric potential field.
